.To all 'whom it may concern.'

Be it known that I, CALVIN B. PATCH, a citizen of the United States,residing at Glenellyn, in the county of `Dupage and State of l Illinois,have invented a certain new and useful Improvement in Side Bearings, ofwhich the following is a full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a partV ofthis specification.

This invention relates to improvements in side bearings.

An object of the invention is to provide a roller side bearing of simpleand relatively cheap construction and one thatl is efficient inoperation. i

In the drawing forming a part of this specification, Figure 1'is a sideelevation of a car body bolster and truck bolster showing myimprovements in connection therewith. Fig. 2is an enlarged vertical.sectional view taken substantially on the line 2 2 of Fig. 1. Fig. 3 isa vertical sectional View taken substantially on the line 3-3 of Fig. 2`Fig. 4 is a toprplan view of the structure shown in Figs. 2 and 3, andFig. 5 is a sectional view, similar to Fig. 3, illustrating another formof my improvements.

ln said drawing 10 denotes the body bolster and 11 the truck bolster,the same being pivotnlly connected at the centers in the usual Imanner.As shown, the body bolster 10, on each side of ,the center thereof,-isprovided with an integral wear plate or thrust member 12 adapted tocooperate with the other bearing'member of the side bearing A. Thebearing member A, as shown, comprises a base plate 13 secured by rivetsor other suitable means to the truck bolster 11, said base plate 13having upstanding spaced lugs 14, 14 each provided rwith an inwardlyturned flange 15 curved on the under side thereof as indicated at 16,the under side 16 copperating with a correspondingly curved face 17fbrmed on the base plate 13 to make an arcuate groove to receive thecorrespondingly curved, routwardly extendedflanges 18 formed on thebottom of a cradle 19Avv'hereby the cradle 19 is rockably mounted =onthe base plate 13. The cradle 19 has formed therein half of `a journalbearing 20, the other half of the bearing being formed in' a cap piece21 de" tachably secured to the member i19 by meansI of bolts and nuts22, 22. The bearing thus Specification of Letters Patent.

formed in the cradle receives a journal 23 on the ends of which areprovided antifriction rollers 24, said rollers being preferably formedintegrally with the journal 23. portion of the journal. bearing isconcaved as indicated at 25 and a portion of the journal 23 is enlargedat the center thereof so as to constitute a central zone of a sphericalV19 without the rollers carried thereby is first inserted with itsflanges 18 in the grooves on the inner sides of the lugs 14, 14.Thereupon the journal with its rollers is put in place and the cap piece21 bolted on and when thus assembled, the rollers 24will. preventaccidental disengagement or separation of the cradle from the basecasting. It will furthermore be noted that all the 'parts may be made inthe 'form of castings, thus producing a device cheap to manufacture.

In the structure shown in Fig. 5, the base casting 113 is provided withspaced upstanding lugs 114A each of which has an elongated slot 115therein, the base casting being also provided with curved bearingsurface 117.. The cradle 119 is curved at the bottom thereof asindicated at 11S to bear on the curved surface 117 whereby the cradle isadapted to rock relatively to the base .-casting( To hold the cradle inposition, a

pin 120 is provided which extends therethrough and into the elongatedslots 115. The journalv and the rollers carried thereby are preferablyof the same construction as the corresponding parts shown in the otherfigures of the drawing. n the construction just described, the basecasting and cradle are provided Awith cooperating shoulders 121, 121 tolimit the amount of rocking movement of the cradle.
